The purpose of this study was to evaluate if there are differences between mesiodistal angulations measurements for all the teeth in constructed 2D panoramic images as compared to 3D measurements. Pre-treatment 3D DICOM data was obtained from the University of Southern California’s patient database and mesiodistal angulation measurements from the constructed 2D panoramic images were compared to 3D coordinate system measurements (gold standard). Thirty three cases were chosen based on the specified inclusion and exclusion criteria. Results indicated that there was a relative trend in the differences in the tooth mesiodistal angulation measurements between the 3D and 2D measurements (p
